Introduction: SARS-Cov-2 first appeared in Wuhan, China, in December 2019 and spread all over the world soon after that. Given the infectious nature ofSARS-CoV-2, fast and accurate diagnosis tools are important to detect the virus. In this review, we discuss the different diagnostic tests that are currently being implemented in laboratories and provide a description of various COVID-19 kits. Areas covered: We summarize molecular techniques that target the viral load, serological methods used for SARS-CoV-2 specific antibodies detection as well as newly developed faster assays for the detection of SARS-COV 2 in various biological samples. Expert opinion: In the light of the widespread pandemic, the massive diagnosis of COVID-19, using various detection techniques, appears to be the most effective strategy for monitoring and containing its propagation.

Introduction the increased prevalence of dyslipidemia in patients with type 2 diabetes mellitus (T2DM) results from uncontrolled hyperglycemia and consistently contributes to an elevated risk of cardiovascular complications. This study sought to estimate the prevalence of dyslipidemia and to investigate the relationship between glycated hemoglobin (HbA1C) and serum lipid levels in Moroccan patients with T2DM. Methods a total of 505 patients with T2DM were included in this cross-sectional study, 77.4% with chronic complications and 22.6% without. The collected data were examined using statistical package for the social sciences (SPSS) version 20.0 software and appropriate statistical methods. Results the data analysis showed that the mean and SD of age were 57.27±10.74 years. Among 505 patients with T2DM, the prevalence of hypercholesterolemia, hypertriglyceridemia, increased low-density lipoprotein cholesterol (LDL-C), and decreased HDL-C was 41.4%, 35.9%, 27.1%, and 17%, respectively. In addition, the data analysis showed that levels of total cholesterol (TC) (p≤0.001), triglycerides (p≤0.001), Low-density lipoprotein cholesterol (LDL-C) (p≤0.001), TC/HDL-C ratio (p=0.006), and LDL-C/HDL-C ratio (p=0.006) were significantly higher in T2DM patients with complications as compared to those without complications. The patients with HbA1C > 7.0% had significantly higher values of fasting blood glucose (FBG) (p≤0.001), total cholesterol (p≤0.001), triglycerides (p≤0.001), and TC/HDL-C ratio (p=0.025) as compared to the patients with HbA1C ≤ 7.0%. The HbA1C demonstrated a significant negative correlation with age (r=-0.139), and positive correlation with FBG (r=0.673), total cholesterol (r=0.189) and triglycerides (r=0.243). Conclusion our results showed that HbA1C is the most important biomarker of long-term glycemic control and can also be a good indicator of the lipid profile.

Emissions of global warming gases continue to rise as the world burns ever more coal, oil and gas for energy. The article, aims to run an investigation nexus between carbon dioxide (CO2) emission per capita and economic growth of energy consumption in over the period 1990-2100. To evaluate the impact of CO2 emission on relative variables, this study verifies that there is positive long-run relationship among CO2 emissions, Electric power consumption and Energy use. This paper also proves bi-directional causality between CO2 emission and electric power consumption (modeling the impact of CO2 emission on output especially in Algeria and because of the vast majority of natural gas is imported from Algeria to Morocco so the authors use the same model for Morocco and compare the results obtained and see what the different causes that influence these results). The policy makers may evaluate exogenous effect to seeking economic growth for global climate warming and to formulate energy policies.

The Death of Industrial Civilization explains how the contemporary ecological crisis within industrial society is caused by the values inherent in unlimited economic growth and competitive materialism. It demonstrates the central role and importance of electricity, and what policy makers need to do in order to ensure that current and future systems remain reliable even as they are transformed by the rise of clean energy technologies. The novel COVID19 pandemic has created an unprecedented global health and economic crisis. The result of such a scenario is that energy demand contracts by 6%, the largest in 70 years in percentage terms and the largest ever in absolute terms. The impact of Covid19 on energy demand in 2020 would be more than seven times larger than the impact of the 2008 financial crisis on global energy demand and this is what the Olduvai theory is defined by e=energy production/population. It states that the life expectancy of Industrial Civilization is less than or equal to 100 years.
